Imagine an object, which has multiple 'slots', which are used to connect that object with other objects. Except that these are not inward pointing slots but the counter parts called 'tangs' (according to this answer).
How would you describe that object, if it has for example 4 tangs?
In German I would call it 'vier-armig' (roughly translates to 'four-armed') since it has four 'limbs'. But four-armed sounds somewhat strange, especially since armed also means carrying a weapon.
Here is a picture to make things clear:
How would you classify the two objects on the right?
